[0043] The utility model discloses can carry out multiple change and can have various embodiment, thus want to illustrate each specific embodiment in the drawing and carry out the explanation to it. But this is not to limit the utility model in the specific implementation, and should be understood as including all changes, equivalents and even substitutes falling into the thought and technical scope of the utility model.

[0044] As Figure 1 The utility model discloses a thyroglossal duct cyst positioning device, including tailorability hose 200 and developer injection part 100,

[0045] The developer injection part 100 and tailorability hose 200 are detachable structure,

[0046] The developer injection part contains developer injection part 110 and two wings 120 and 130 and is three -way's modeling, and the both ends of two wings 120 and 130 are provided with limiting protruding structure 121 and 131, and limiting protruding structure, developer injection part are located three passageways of three -way respectively, can accommodate the inflow and outflow of liquid,

[0047] The diameter of limiting protruding structure 121 and 131 is greater than the diameter of tailorability hose, so that the sleeve is nested with the limiting protruding structure when using, just can realize the effect of clamping, avoid its slip, and can prevent the leakage of the developer in it,

[0048] The developer injection part 110 has one-way valve structure 111, that is, adopts the material such as rubber rubber that can elastically stretch and contract as seal, and the middle part is a split, and the injector can inject the developer inward from the split position, and when the injector is separated, the effect of closing can be directly realized due to the elasticity.

[0049] Considering the leakage problem of the developer, the injection inlet of the developer injection part can also be provided with an opening and closing mechanism, that is, a cover or similar structure.

[0050] Considering that it is generally formed into a ring shape, as Figure 2 The developer injection part can be designed into a modeling with an arc, or the developer injection part is made of a material with variability, and can be deformed according to the modeling of the hose during use.

[0051] As Figure 3 In another example, the limiting protruding structure has a hook-shaped edge or protrusion 122 and 133,

[0052] In order to cooperate with the hook-shaped edge or protrusion 122 and 133, the inner surface of the tailorability hose is uniformly provided with a plurality of limiting mechanisms; the limiting mechanisms are engaged with the structure of the hook-shaped edge or protrusion 122 and 133.

[0053] Preferably asFigure 4 As shown, the limiting mechanism 210 is in the form of a groove, and in use, the protrusion is just clamped in the groove to achieve clamping of the two.

[0054] Alternatively, in order to cooperate with the hook-shaped edge, the limiting mechanism can also be a protruding member obliquely arranged on the inner surface of the cuttable hose to achieve the effect of buckling.

[0055] Considering that the device is generally arranged at the throat of the human body, even if the situation is lying down, it is easy to cause the problem of falling due to slight movement, so in the scheme of the embodiment, a positioning mechanism is also arranged to prevent falling,

[0056] Design 1. The positioning mechanism is a sticking member arranged on the bottom surface of the cuttable hose and / or the developer injection member, such as a double-sided adhesive tape with sticking function.

[0057] Design 2. The positioning mechanism is a gas bag type inflatable ring 1 as shown. Figure 5 The gas bag type inflatable ring is different from the traditional neck fixing ring, and the opening and closing position is at the side edge, and the ring is closed by a buckle or a sticking buckle 3, and the inflation and deflation is performed by a balloon 2.

[0058] The gas bag type inflatable ring 1 has a ring-shaped mounting groove 2, which corresponds to the throat, and when the patient wears it, the left and right fine adjustment is performed according to the position required for detection.

[0059] The ring-shaped mounting groove 2 is a thyroid tongue cyst positioning device, which is embedded in the ring-shaped mounting groove to achieve the problem of positioning without falling.

[0060] Based on the above design, a thyroid tongue cyst positioning device capable of injecting developer, adjusting size and deforming is realized, and when it is used for clinical examination, the image effect is very clear, and the relationship between thyroid tissue and tumor can be more accurately identified.

[0061] Although the above has been described centering on the embodiments, this is only an example and does not limit the present application, and those skilled in the art will clearly understand that various modifications and applications not exemplified above can be made within the scope of the essential characteristics of the embodiments. For example, the various constituent elements specifically shown in the embodiments can be modified and implemented. Moreover, various differences related to such modifications and applications should be interpreted as being included in the scope of the present application defined in the appended claims.
